I have valerian growing absolutely everywhere destroying the dash on my walls by huge roots growing behind, its a weed to me although bees love it and colour is lovely. Is there any way to keep this plant in check? I’ve found it impossible to kill the roots. i don’t want to kill it all but would like to be able to control it a bit. grateful for any suggestion. thanks
